20 STUDIES ON AUSTRALIAN MOLLUSCA, 



PupiNA CROSS EI, Brazier. 



Pupina crossei, Brazier, Proc. Linn. See. N.S.W. i., 1876, p. 110. 



(Plate iii., fig. 38.) 



One of the type shells in the Macleay Museum is here 

 illustrated. It is from Palm Island (I understand the most 

 northern of that archipelago was the only one visited by the 

 Chevert Expedition), and is 7 mm. in length. 



Pupina nitida, Brazier. 



Fiipiaa nitida^ Brazier, Proc. Linn. Soc. N.S.W. i., 1876, p. 136. 



(Plate iii., fig. 37.) 



One of the original lot from Barrow Island is here figured. It 

 is 9 mm. in length. \ 



Sitala reedei, Brazier. 



Helix {Conidus) reedei, Brazier, Proc. Linn. Soc. N.S.W. i., 

 1876, p. 101. Helix (Conulas) inaino, Brazier, loc. cit. Comdiis 

 mairio, Hedley, op. cit. (2), vi., p. 75, pi. ix., f. 6. Sitala maino, 

 Hedley, op. cit., ix., p. 384. 



(Plate iii., fig. 45.) 



A specimen from Darnley Island (height 2*5, major diam. 3*4, 

 minor diam. 3 mm.) is here figured. I cannot distinguish this 

 from the New Guinea S. maino, which I therefore suppress as a 

 synonym. Because it is not of Latin form, the name maino is 

 not as acceptable as reedei. 



Sitala nepeanensis, Brazier. 



Helix (Conidus) nepeanensis, Brazier, Proc. Linn. Soc. N.S.W. 

 i., 1876, p. 102. 



(Plate iii., figs. 40-42.) 



One of the type lot from Nepean Island is here figured. The 

 dimensions of it are : height 2*6, major diam. 3*64, minor diam. 

 3-48.
